Global study finds the food commodities driving major global deforestation; Beef on top

A farmer clearing land for maize in one country, a rice field expanding in another. These local decisions, repeated millions of times, are now linked to a global pattern of forest loss.

New research from Chalmers University of Technology, a Swedish research institution, finds that staple foods consumed daily are driving more deforestation than many export crops long associated with environmental damage.

The study, published March 23, combines satellite land use data with agricultural statistics to map how 184 commodities have contributed to forest loss across 179 countries.

It offers what researchers describe as the most detailed global picture yet of how food production shapes deforestation.

Staple crops deforestation impact compared to cocoa coffee rubber

The analysis shows that maize, rice and cassava together account for about 11 percent of agriculture driven deforestation worldwide.

By comparison, cocoa, coffee and rubber combined account for less than 5 percent.

This contrasts with the dominant narrative that focuses heavily on export oriented commodities such as palm oil and soybeans.

Lead author Chandrakant Singh said earlier research has often centered on a narrow set of crops and regions.

“Deforestation’s links to food production have long been studied, but have often focused on some products, such as beef, soybeans and palm oil, which are well known in the context of deforestation,” Singh said in a statement released by Chalmers University of Technology.

The study confirms that beef production remains the single largest driver, responsible for about 40 percent of global deforestation linked to agriculture. Palm oil accounts for 9 percent, while soybeans contribute around 5 percent.

Staple crops differ in one key way. Their impact is spread across many regions rather than concentrated in a few hotspots.

Unlike palm oil in Southeast Asia or soybeans in South America, maize, rice and cassava are grown widely for domestic consumption, making their environmental footprint more diffuse and harder to track.

Agriculture driven deforestation global data and carbon emissions findings

The researchers estimate that 122 million hectares of forest were lost due to agriculture driven deforestation between 2001 and 2022. More than 80 percent of that loss occurred in tropical regions.

The study also examined carbon dioxide emissions linked to deforestation, often caused when forests are burned to clear land for farming or grazing.

Total emissions over the period were estimated at around 41 billion tonnes of carbon dioxide, averaging close to 2 billion tonnes annually.

That figure is lower than previous global estimates, which had placed annual emissions at more than twice that level. Singh said the difference reflects a more detailed method of linking specific commodities to land use changes.

Even at the lower estimate, agriculture driven deforestation accounts for about 5 percent of global carbon dioxide emissions, according to the study.

Domestic food production role in deforestation policy response

Co author Martin Persson said the findings highlight the need to look beyond international trade when addressing deforestation.

“The debate on deforestation has circulated a lot around how people in rich countries like ours cause deforestation with our commodities imports, and this is absolutely important to get to grips with,” Persson said.

“But we mustn’t forget that a large proportion of deforestation is driven by agricultural production for domestic markets.”

The study suggests that policies focused only on supply chains linked to exports may overlook a significant share of forest loss driven by local food systems.

Researchers say their Deforestation Driver and Carbon Emissions model, known as DeDuCE, could help governments, companies and civil society identify where interventions are most needed.

The model links specific commodities to deforestation patterns, offering a tool for more targeted decision making.

Singh said future work will expand the model to include non food sectors such as mining and energy, which also contribute to forest loss.

For now, the study reframes a familiar issue. The drivers of deforestation are not only tied to global trade or distant markets.

They are also rooted in everyday food systems.

Europe Deforestation to Double, Predicts AI Study Citing Fires, Storms and Bark Beetles

A new study estimated the extent to which the area covered by Europe in forest could be disturbed by fire, storms, and bark beetles by the year 2100 in varying climate conditions. With satellite data and forest simulations, an artificial intelligence model predicted the disturbances on a continental scale using 13,000 points in Europe.

In every case, disturbances of the forests in the future were greater than it is today, with great impact on forests and services to the society.
There is a significant effect of wildfires, storms, and even bark beetles on forests and the benefits that they bring to people and environment.

This is the first time when a big international team of researchers at the Technical University of Munich (TUM) has computed how disrupts would alter the forests in Europe in the year 2100. In even the most optimistic of scenarios, the team does project a significant expansion of the damaged forest area, in the worst case, the disturbance might even be doubled.

It is not novel that trees die, and in fact, it is a normal process in the forest that is in the process of natural dynamics whereby old trees die, young trees regenerate and become the next generation of canopy trees.

The new thing is the magnitude of how wildfires, storms, and bark beetles are transforming forests due to the change of climate. The amount of forest destruction in Central Europe demonstrated dramatic figures in recent years, however until this time it was unknown how much the area covered by forests could be deterred by future disturbances. The disturbances define the carbon storage capacity of the forests, the timber they are capable of offering, and the habitats of which species they are able to offer, thus making the results very significant to the policymakers and society.

A great number of researchers headed by Professor of Ecosystem Dynamics and Forest Management, Rupert Seidl, TUM, has now filled this gap in knowledge. The researchers have approximated that, the space disrupted by fires, storms, and bark beetles might increase threefold by 2100 with a global warming of slightly above 4 degrees Celsius.

The researchers used remote sensed data as a reference point between 1986 and 2020, a timeframe that experienced abnormally high disturbance in the forests. Although it is in the best scenario, the researchers are projecting increased destruction of forests in future compared to this reference period even with the warming of about 2 degrees Celsius.

Regional differences

In combination with 13,000 simulations of forests in Europe, the model was an AI-based simulation, which was trained on 135 million data points of forest simulations and multi-decadal satellite data of forest disturbances. This enabled them to model how the forests would develop in future and how disturbances would occur and penetrate to the scale of a single hectare providing very accurate information on regional variation in future forest disturbance patterns.

The study has indicated that forests in Southern and Western Europe will be affected especially and will experience the strongest forest disturbances.

The overall impact of the future on Northern Europe is less expected to be severe, though the hotspots of the future forest damage are predicted to appear as well. According to Rupert Seidl, disturbances are becoming a cross-regional problem, that is, they destroy timber markets in Europe and endanger the ecosystem services that forests bring to society.

The study authors hence regard the growing disturbance rates as being an urgent demand on forest policy and management to consider: “We should be ready to witness a lot of forest damage in the near future. On the one hand, this implies that we have to prepare and cushion against more severe changes in the services forests offer. Conversely, disruptions also provide a chance to create new and climate-resistant forests – they are agents of change,” said Seidl.

Forestry has to meet the threat and the opportunity of increasing the level of disturbance, with the help of new scientific techniques and knowledge, explained Seidl.

Giraffes, parrots, oak trees, cacti among many species facing extinction

It may be surprising to learn that even giraffes, parrots, and oak trees are included in the list of threatened species, as well as cacti and seaweed.

Seaweed is one of the planet’s great survivors, and relatives of some modern-day seaweed can be traced back some 1.6 billion years. Seaweed plays a vital role in marine ecosystems, providing habitats and food for marine lifeforms, while large varieties – such as kelp – act as underwater nurseries for fish.

However, mechanical dredging, rising sea temperatures and the building of coastal infrastructure are contributing to the decline of the species.

The world’s trees are threatened by various sources, including logging, deforestation for industry and agriculture, firewood for heating and cooking, and climate-related threats such as wildfires.

Kelp, a type of seaweed, can be fed to animals and could help to reduce greenhouse gas emissions.

It has been estimated that 31 per cent of the world’s 430 types of oak are threatened with extinction, according to the International Union for Conservation of Nature (IUCN) Red List of threatened species. And 41 per cent are of “conservation concern”, mainly due to deforestation for agriculture and fuel for cooking.

Giraffes are targeted for their meat, and suffer from the degradation of their habitat due to unsustainable wood harvesting, and increased demand for agricultural land; it’s estimated there are only around 600 West African giraffes left in the wild.
